Zusammenfassung:The physicochemical characteristics of the carbon material produced by methane conversion in UHF discharge plasma are determined. The material is characterized by high carbon content (99.4 wt %); the calorific value is 32.7 MJ/kg; and the packing density is 25.5 kg/m 3 . According to X-ray phase analysis, the crystalline content of the sample is ~43%. Morphologically, it consists of spherical agglomerates (no larger than 20 μm) composed of numerous nanoparticles. The mean particle size is 80–120 nm; the specific surface is 51.2 m 2 /g; and the mean pore volume is 0.25 cm 3 /g.
